The First Ones evolve, and the first of the First Ones is a being called Lorien. His race are the first to find the Shadows and the Vorlons. The First Ones are vast, timeless beings who go out into the galaxy and found great empires, explore beyond the Rim and teach the younger races as they emerge.

In The Shadow Of Z'ha'dum. In Whatever Happened To Mr Garibaldi? Lorien describes himself as the first of the First Ones, he was old even before the Earth solar system formed. Into The Fire establishes Lorien's race were the first to find the Shadows and the Vorlons.

Author's note: Obviously Delenn wasn't told about this earlier race by the Vorlons.

A gateway is constructed leading to a dimension parallel to this universe and they are exiled into it for their crimes. From their exile, these First Ones are still able to watch our universe. A record of their deeds is kept in the ancient underground city with a warning to be wary of their return. Over the eons they, the gateway and city almost pass from memory.

The Legend Of The Rangers:To Live And Die In Starlight.

circa 3 Million Years Ago.

The Vorlons come to Earth and genetically manipulate the primitive ape men they find there, to view them as the Vorlons wish to be seen, rather than in their natural glowing jellyfish like form. The Vorlons repeat this exercise with many other evolving races throughout the galaxy.

Conjecture. In The Shadow Of Z'ha'dum,Kosh cannot leave his encounter suit as he would be recognised by everyone, a fact borne out in The Fall Of Night when he left his suit to fly to Sheridan's rescue. Each race saw Kosh according to the legends of their world, hinting at Vorlon manipulation that is revealed by Morden in Z'ha'dum. Matters Of Honor suggests the Vorlons use telepathic projection to hide their form. Falling Toward Apotheosis reveals the Vorlons true appearance.

circa 1.5 Million Years Ago.

After travelling to many worlds manipulating the races to see them as beings of light and being revered as gods, the Vorlons start to think they are gods, superior to the universe that created them. Believing they could transcend this dimension, the Vorlons apply all their knowledge and wisdom to create a gateway into another universe. In their pride, they did not think to what lay on the otherside of the gate and let loose a race older than them, more powerful and all of them telepathic. This alien race was destroying all life in their own universe because they believed only they had the right to exist, all the other races were inferior and had to be exterminated. Modifying the gate to enhance their telepathic inpulses, the aliens create an army of Vorlons willing to die for them. Those Vorlons not being controlled fight back, disabling the gate to prevent any further intrusions. Before it can be destroyed, those still under telepathic control drop the gate into hyperspace to hide it. The memory of their mistake is passed from generation to generation of Vorlon.

Thirdspace. The carbon dating result on the Vorlon gateway shows it is over a million years old.

Author's note. Is it possible that the beings the Vorlons released into our universe when they opened the gateway were the First Ones exiled billions of years earlier? If so, it leads to the interesting notion that these may have been from Lorien's race as they were older than the Vorlons.

On a visit to Earth, the Vorlons take gene samples from the population of Homo erectus. Visiting other worlds and repeating the genetic harvesting for their experiments, the Vorlons begin re engineering the DNA to produce the first telepath genes at their chief experimental station.

The Nautilus Coil.

circa 1 Million Years Ago.

Many of the First Ones tire of looking after the younger races. Some disappear beyond the Rim never to be seen again, while a few remain to walk openly among the races barely aware of their existence, in pursuit of tasks incomprehensible to them. The Shadows and the Vorlons acting as guardians to the younger races, begin warring with each other over how best to help them evolve. The Vorlons favour evolution by control and the Shadows by creating conflict. Each side abides by rules of engagement laid down by Lorien, respecting each others position.

In The Shadow Of Z’ha’dum, Voices Of Authority and The Summoning reveal the fates of many of the First Ones and the reason for the war between the Shadows and the Vorlons. The Passing Of The Techno-mages:Invoking Darkness reveals Lorien set down the rules.

An unknown intelligence genetically engineers a race of living biological recorders called Vendrizi. These genetically neutral symbiotic beings record all aspects of their host culture as a means of preserving it should anything happen to that civilisation. The Vendrizi accomplish their tasks by joining with those in society who have lost hope and a sense of purpose in their lives. As each culture moves out into the stars, the Vendrizi go with them ready to move onto a new civilisation.

Exogenesis. The Vendrizi reveal their history to Marcus and Franklin.

circa 8,740 Years Ago.

Having abided by rules of engagement, the Vorlons decide their way of helping the younger races to evolve is the right way. So when the Shadows begin encouraging conflict between worlds according to their own evolutionary doctrine, they are fought to a standstill by the remaining First Ones and driven back to their stronghold on Z’ha’dum. The First Ones go into hiding, watching and waiting for the Shadows return. This is the last time they walk openly among the races.

In The Shadow Of Z’ha’dum. Delenn says the last great war with the Shadows was 10,000 years ago.

Author’s Note: I am assuming that Delenn meant 10,000 years before the Great War of 1260-1261.

Many try to slip away, but along with the ships Captains that transport them, they are arrested and executed.

Secrets Of The Soul. The law was passed 1200 years ago.

Defeating a Xon army at the Battle of Scoria Plains, Emperor Morell and his troops are resting near the river Tuwain when he meets Malia, the prophetess of the village of Tuwain. She foretells of a great danger facing Morell and that a dagger would strike to his heart from near his heart and his life would be forfeit unless he heeded her warning. Asking how he could avoid this death, Malia speaks only of the crescent moon hidden in darkness. Wanting nothing in return for her prophecy except Morell’s good wishes, his troops return to the Royal palace where a great banquet is held in his honour. With his wife Celina and his family gathered round, Morell’s favoured nephew Elfeni stands to raise a toast when Morell notices the crescent moon brooch on his tunic hidden by the shadow of his arm. He cries out to the guards who seize Elfeni as he is about to strike the Emperor with a blade. Under questioning, Elfeni confesses to an alliance with others who would bring civil war and make him Emperor. With his life saved by prophecy, Emperor Morell returns to Tuwain and gives Malia a tenth of his fortune pledging that while an Emperor sits on the throne there would always be a prophetess in Tuwain who would always be in Royal favour. Over the years as one prophetess died and another took the title, the Emperor would make the journey to Tuwain for her inauguration.

After suffering half a dozen invasions of their homeworld, the leaders of Ikarra 7 decide to build the perfect weapon to defend themselves. The scientists create twelve machines, bioorganic in construction, capable of intelligent thought with the ability to adapt to any situation and meld with a living being. The machines personality matrix is formed from the brainwave patterns of researcher Tu'Lar and programmed with what it is to be a pure Ikarran. When eleven warriors are activated to save Ikarra from another invasion, they turn on their creators, wiping out the planet's population because they did not match the restrictive and idealistic definitions of the machines programming. The eleven machines eventually wear out through neglect.

Infection. Ikarra 7 has been dead for 1000 years. Franklin discovers the fate of the Ikarrans.
